This edition of the Big Bang Guide is both exactly what it claims to be and exactly what you probably don't want for your players. Focused on the weapons of the Gulf War, this edition contains some great information on the small arms and AK-47 variants used by the various combatants. However a lot of the page count is filled out with missiles, rockets, and heavy weaponry. It's all good information and as meticulously detailed as other Big bang weapon descriptions, but the weapons themselves are probably too destructive for the standard D20 Modern-style campaign.

That said, there is a lot of good stuff here. Ever since I bought my first Big Bang Guide I have wished that Alternate Realities would put out editions with a more unified theme, such as a guide focused on handguns, or one focused on sniper rifles. I'm still waiting on those, but this edition does give an excellent overview of the tools used in the Gulf War. And although some may find the level of detail on each weapon to be daunting, I've found that the extensive descriptions make the individual weapons more "real". This is especially useful in D20 Modern games, where most weapons have very similar game statistics.

For those GMs thinking about running a Gulf War campaign or sending characters into combat zones, this edition of Big Bang is an excellent resource. For the rest of us it still has enough regular weapons to be worth a look, although I'm still waiting for the comprehensive Big Bang Guides to handguns, sniper rifles, SMGs, etc.
